you may need to study these related web exercises:
Basic Concepts Involved in Factoring Trinomials
Factoring Trinomials of the Form x2 + bx + c , where c > 0
Factoring Trinomials of the Form x2 + bx + c , where c < 0
Here, you will practice factoring trinomials of the form x2 + bx + c ,
where b and c are integers.
EXAMPLES:
Factor: x2 + 5x - 6
Answer: x2 + 5x - 6 = (x - 1)(x + 6)
Factor: x2 - 5x - 6
Answer: x2 - 5x - 6 = (x + 1)(x - 6)
Factor: x2 + 3x -7
Answer: x2 + 3x -7 is not factorable over the integers
Factor: x2 + 5x + 6
Answer: x2 + 5x + 6 = (x + 2)(x + 3)
Factor: x2 - 5x + 6
Answer: x2 - 5x + 6 = (x - 3)(x - 2)
If a trinomial is not factorable over the integers, then key in "NF" for your answer.
